  • Oil-based drilling fluid recovery and reuse
    Patent number: 8997896
    Abstract: Methods and related systems are configured to treat a drilling fluid to cause water droplets to coalesce. One or more phases are thereafter separated from the treated drilling fluid. The oil and/or solids separated from the treated drilling fluid may be added to a base fluid.
    Type: Grant
    Filed: March 2, 2011
    Date of Patent: April 7, 2015
    Assignee: Baker Hughes Incorporated
    Inventors: David E. Clark, Lirio Quintero, Anuradee Witthayapanyanon, Alexander John McKellar, Martin Gilbert
  • Nanoemulsions
    Patent number: 8822385
    Abstract: Nanoemulsions have been discovered to be useful to the oil field. More particularly water-in-oil (W/O), oil-in-water (O/W) and other classes of nanoemulsions have found beneficial application in drilling, completion, well remediation and other oil and gas industry related operations. Additionally, nanoemulsions may reduce friction pressure losses, as well as reduce subsidence of solid weight material during oil and gas operations. New preparation methods for nanoemulsions have also been discovered.
    Type: Grant
